RFA: NEWS update

[Tom Tromey]

This updates NEWS to account for the template parameter support.
I added a "C++ Improvements" section because I know we will be adding
more stuff here before 7.3.

Ok?

Good idea, thanks.

Can the entry elaborate a bit more about this?  I'm afraid I was
unable to understand what will the improvement mean to me as a C++
programmer.  "Puts template parameter in scope" is somewhat cryptic,
IMO.

Thanks.

Perfect.  Thanks.

This "then" should not be capitalized, as it doesn't really begin a
sentence.

I'm committing it with that change.
